Abstract
The invention relates to a method for transmitting a clock rate on a network link, seat of a speed timing signal (DR), consisting of at least synchronizing (A), at an input point (I) of this network, this speed timing signal with a reference external clock rate (ESR) for generating a synchronized speed timing signal (SDR) propagating on the network, and of extracting, at an output point (O) of the network, the reference external clock rate (ESR) from the synchronized speed timing signal (SDR) for utilization. The invention is for providing networks that are seats of a speed timing signal such as FastEthernet and Gigabit Ethernet networks or of higher speed Ethernet networks.
